1969 F250 won't start anymore

[willowbilly3]

When you flood an engine bad it washes the oil film off the cylinder walls and you loose much of your compression. Sometimes enough that it won't start even after you dry out the plugs. Usually, but not always, you can get it fired up by puttig some oil down the spark plug holes and spin it over a few times. It makes a mess but it works best to crank it over before you put the spark plugs back in. And also check the oil for dilution as it usually needs changed too after al that gas gets past the rings.

This is just my most probable scenario for what you described, it may in fact not be this problem at all. Have you checked the choke for opening? Is it closed? Have you tried propping it open and arrempting to start the engine?
